It features a 55-degree triangle (D-shape) geometry with a neutral hand orientation and a 0.0156 inch corner radius. The insert is manufactured from solid carbide with a CVD-applied multilayer coating of Al2O3, TiN, and TiCN in the 4425 grade. This combination of substrate and coating targets steel and cast iron workpiece materials, making it a reliable choice for general turning, profiling, and facing passes in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium to roughing turning applications in both production shops and job shops running steel and cast iron components. The XM chip breaker geometry supports stable chip formation across a range of feed rates and depths of cut. The DNMG form factor with clamp and screw holding method fits standard DNMG toolholders commonly found on manual and CNC turning equipment. Licensed machinists, CNC operators, and tooling specialists are the typical end users for this insert type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDNMG 15 06 04-XM geometry with 55-degree included angle and neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eCVD multilayer coating: Al2O3, TiN, and TiCN for heat and wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e4425 grade carbide substrate optimized for primary workpiece material codes P and K\u003c\/li\u003e\n  \u003cli\u003e0.0156 inch corner radius for moderate finishing and medium roughing work\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch inscribed circle with 1\/4 inch insert thickness\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and screw insert holding methods on standard DNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard DNMG-style toolholders accepting the 15 06 04 insert size.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench for clamp screws to avoid cracking the insert or damaging the seat. Inspect the insert pocket and shim seat for wear or debris before seating a new insert, and verify tool offset compensation after each index.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (55-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: XM (G)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3, TiN, TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 15 06 04-XM 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7861278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749411520818,"sku":"7861278","price":377.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddd315dddf815b98979763da5196b383.jpg?v=1788905747","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861278-turning-insert-dnmg441-xm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
